Name

drm_rect_calc_hscale_relaxed — calculate the horizontal scaling factor

Synopsis

int drm_rect_calc_hscale_relaxed (struct drm_rect * src,
 struct drm_rect * dst,
 int min_hscale,
 int max_hscale);
 

Arguments

src

source window rectangle

dst

destination window rectangle

min_hscale

minimum allowed horizontal scaling factor

max_hscale

maximum allowed horizontal scaling factor

Description

Calculate the horizontal scaling factor as (src width) / (dst width).

If the calculated scaling factor is below min_vscale, decrease the height of rectangle dst to compensate.

If the calculated scaling factor is above max_vscale, decrease the height of rectangle src to compensate.

RETURNS

The horizontal scaling factor.
